Can Official Messaging on Trust in Elections Break Through Partisan Polarization?

Partisan actors in the US have recently politicized trust in elections. In combination with partisan polarization, politicized election administration could undermine the peaceful transfer of power following elections. Can messaging about trust in elections break through partisan polarization? Partnering with election officials from Los Angeles County, Colorado, Georgia, and Texas, we conducted messaging experiments with nearly 8,500 Americans following the 2022 US midterm elections. We find that state and local election officials can be strongly effective at increasing trust in their own state elections. Our estimate suggests that one 30-second official message increases trust in elections by about one-fifth of the pre-treatment difference between Democrats and Republicans. Additionally, videos explaining protections on election integrity in Arizona and Virginia increase trust in elections outside the respondents' own states. Our results suggest that election officials can break through partisan politics and play an important role in rebuilding trust in the democratic process.
